There a lot of products and ways that
you can improve your 944 Turbo. Here is a low-dollar item
that can genuinely help your car to start, run and look
better. It only takes about an hour to install this kit and
it can be done by just about anyone with a little mechanical
aptitude. Included in the kit are:
- O-rings to replace the throttle
body shaft seals. These seals are important because they
prevent vacuum leaks that can alter the smooth engine
idle. These seals also protect the Throttle
Position Sensor (TPS) during boost. A damaged or
worn-out seal can result in oil being forced into the
TPS and damaging it - TPSs are expensive (over $100
each). A secondary TPS o-ring, as well as a throttle
body-to-intake flange o-ring and an o-ring for the brass
air valve are also included.
- Stainless steel fasteners to
replace the old ones. These fasteners are marine quality
and the best looking fastener that can be found. Also included
are hex cap screws for throttle body mounting, hex cap
screws for TPS mounting and new stainless nut and
stainless, serrated washer for the throttle cable cam.
Also included are specially machined stainless steel
screws for securing the throttle plate. All of these
fasteners look good and stand up well to
corrosion. The TPS screws provided are hex socket
head (rather than the OEM Phillips). This allows for
adjustment of the TPS while installed on the engine -
this small feature alone is a worthy upgrade.
- The kit includes 7 pages of
step-by-step instructions with over 20 black-and-white
photos to show exactly how every part of the throttle
body is disassembled, inspected and resealed.
Special note; these o-rings are NOT
original Porsche parts. All but the shaft O-rings are identical in size,
shape and material. The shaft o-rings are replacements for Porsche's wiper
seals. These o-rings were selected and tested carefully to provide a very
good seal (up to approx 25 lbs per sq in.) without presenting significant
drag on the rotation of the shaft.
This kit is for all years of the 944 Turbo. Below are a few
of the photos used in the instructions:
